To all whom it may concern.

Be it known that I,

dent oll the city ofChicago, county of Cook, and State of Illinois, have invented certain new and yuseful Improvements in Candy- Molding Machines, of which the following is a specification. p A

My invention relates t0 improvements in candy molding machines and has -for Vits object .the provision of an improved construction ot thischaracter which is of simple construction and'highly efficient in operation, f Y

Y The invention consists -in the combinations yand arrangements of parts hereinafter described andclaimed. l 'g The inventionV will be best understood by reference to the accompanying drawings iiorming'a part `of this specification, v'and 1n which,

Figure 1 is a side view of a molding machine embodying theinvention,

)Figal 2, a detail view showing an ecfentric-and cam employed inthe construction, y

Fig. 3, a transverse section of themachine, if 1 Figs. 4, 5 andfG, detail sections illustratingdifferentpositions of a `'slide valve em# `ployed in the machine, and y l Fig. 7,1a V:sectiontaken'on line 7-7 Y of rllhe preferred form of construction as illustrated in the drawings comprises a suitable traine 'or'standard 8 having a feed hopper or receptacle 9,arrange'd centrally over .the -top thereof, said hopper being f equipped with a weighted `piston 10 adapted to exert pressure ,on material in saidhopper. Two molding chambers 11 'are v,formed at the bottom o'l' hopper9 in open. communicai tion therewith through passages 12, and a slide valve 13 is provided for controlling said passages. The valve 13 v1s provided with two ports 14 arranged 'to' be thrown into andfout of registration with passages 12, and said valve is operated by 'means of a lever 15 pivoted `at 16 to the frame of the machine and having its lower end running in a cani groove 17 in the periphery of a cani disk 18, as shown, thearrangement being such as to cause reciprocation of the slide valve 18 upon revolution of the cam 18. CamlS is'mountedfon .the master shaft 19 of the machine, said `master shaft being @LammV W. Birnen, pulley 20,

a citizen of the United States, anda resicated iny Fig. 5, the mold chambers y11 will Abe'filled with lthe candy material, which is I'force the'molded candy 'downwardly from. the mold chambers l11, as indicated'ln-F ig.

drivenby means of a belt operated on The valve 13 is provided Vwith two sets of` `'air poirts21 in communication with a passage 22 supplied with air under pressure thipug'h a flexible liose or `tube V23. Tube 23 connects with a pipe 23. leading into the upper portion of `'an oil chamber 24,which isr closed lat the top, and another. pipe 25 leads 'rom the lower portion. of the oil chamber 24 to acompressed air'supply tankv v26, the arrangement being suchthat when slide valve 13 moves into the position Vindiplaced in hopper 9 ina plastic State. Then fthe supply of candy is cut olf by the inovement of lvalve 13,- and jports 21 brought into the position indicated in Fig.L 6, to

6, the oil-carried away by vthe airv passing through oil-'chamber 24 serving to lubricate the walls of the` mold chambers,rv to prevent sticking of the candy. j l K Ay-com'bin'ed closureand supportin plate 27 is arranged under the mold-chain ers 11 and yieldingly supported by means of springs 28 on a vertically reciprocating table 29, connected bylinks 30 withec'cen-` trics 31ion shaft 19, the arrangcmentbeing i Vsuch that lwhen themold chambers 'l1 arel being filled with material, the closure and v,support "2,7, is yieldingly `held against` the *underside/of hopper 9 to `form a closurefor the open lower Aends of -mold chambersll.

WVhenvalve '13 shifts to admit the air into the l mold chambers, the support; 27 `is with- 'drawn'fto permit V'of the.discharge ofthe V mol'ded candy from said `mold chambers. 95

An endlessbelt conveyer `T32 is arranged to Vtravel across the frame 8 of the machine` over the closure and support 27, and is equipped with a weighted tension roller 32 which maintains the .tension in said con- 100 veyer, which permits of the movements of Y -plate 27. The conveyer 32l operatesA over suitable" rollers as indicated, and is intermittently driven bymeans cfa ratchet 33 and'pawl |armjei oscillated by a link 35 ,105 Vhaving a slotland pin Vconnection v36 with I the face of the cam member 18, as will be readily understood, to produce an-intermittent feed of the beltconveyer 32. A strip ofparained paper 37 is arranged to travel 111) Y the appended claims.

across the top of plate being Withdrawn from a roll 38 by the action of said conveyer. The strip 37 is thus arran ed to receive the molded portions ofk cancy discharged from the molding chambers l1V at .eachoperatiom and serves as. a means for 'ready removal of said candy and disposition of the same. While I Ahave illustrated and described Y the preferred form of' construction for carble of variation `and modification Without departing :from the spirit of the invention. I, therefore, do not Wish to be limited to the precise details of construction set forth, but desire' toavail myself of such variations and modifications as come within the scopepof VHaving described my invention claim as new and desire to secure by Letters )Patent is .l L
